Advanced Thermodynamics

This course tries to enhance the understanding of thermodynamics principles and their relevance to the problems of humankind; providing the student with experience in applying thermodynamic principles to predict physical phenomena and to solve engineering problems. Fundamental laws of thermodynamics and their application to energy systems; and the concept of exergy and exerg-economic to various energy systems; introduction to thermodynamic relations and chemical thermodynamics, and phase and chemical equilibrium; thermodynamics of combustion systems, will be studied. A final course project will be assigned to students to link the fundamental concepts with practical, real-world problems.

Advanced Fluid Mechanics

This course provides principal concepts of fluids and fluid flows. Introducing the physics and developing solution methods for various viscous flows using proper assumptions and physical boundary conditions are the main part of the course. Topics include fluids and flow properties, conservation equations, preliminary continuum mechanics, Navier-Stokes equations and exact solutions, similarity solutions, boundary layer theory and separation, laminar boundary layer, introduction to instability and turbulence.

Advanced Heat Transfer

This course is intended to deepen the fundamentals of heat transfer by covering advanced topics in convection, conduction and radiation. Course contents include the] conservation laws, transient and steady-state heat conduction, forced and free convection, thermal boundary layers, heat transfer in laminar and turbulent flows, radiative heat transfer, estimation of view factors and emissivities, combined conduction, convention and radiation heat transfer, heat transfer with phase transformation, heat exchangers, and analysis of heat transfer equipment efficiency.

Advanced Combustion

The objective of this course is to provide the fundamental principles for graduate students involved in research on any aspects of combustion and reacting flows, including power generation, various engines, and furnaces. Topics covered include chemical thermodynamics; equilibrium chemistry; chemical kinetics; conservation equations; the structure of laminar premixed, diffusion, and partially premixed flames; droplet combustion; turbulent premixed combustion; turbulent diffusive combustion; combustion instabilities; and the ignition and extinction of flames.

Advanced Energy Systems

Energy systems exist in various forms to fulfill human needs. Besides, advanced technologies have assisted energy systems to improve their efficiency and reduce their emissions. Thus, understanding how advanced energy systems work is of great importance. This course help graduate students to learn how to model, simulate, analyses and assess advanced energy systems and come up with new ideas to improve the systems performance. Energy resources, advanced thermodynamic cycles, energy and exergy analyses, advanced combined cycle power plans, waste heat recovery technologies, hydrogen production methods, SOFC and PEM fuel cell and their applications, advanced refrigeration systems, renewable-based advanced energy systems, and integrated multi-generation energy systems will be studied and a final course project will be assigned to each student.

Computational Fluid Dynamics

This course is an introduction of employing finite-volume method and numerical techniques for solving the fluid flow equations. Topics covered include dimensionless form of the fluid flow equations, error analysis, basics of discretizations, fundamentals of finite-volume method, stability and accuracy analysis of a numerical method, and implementation of finite-volume method to Poisson, Wave, Energy, and Navier-Stokes equations as course projects.

Optimization of Energy Systems

For various reasons, it is essential to optimize processes so that a chosen quantity, known as the objective function, is maximized or minimized. This course will try to explore the use of optimization in energy systems applications by introducing objective functions, constraints, and decision variables. Several optimization techniques will be introduced, and their applications will be highlighted. Since in energy engineering there might be several objective functions that need to be optimized simultaneously, multiobjective optimization methods using evolutionary algorithms will also be covered, and students will learn how Pareto curve is obtained from optimization, and their application in several practical examples such as power plants, petrochemical plants, desalination systems, and building technologies will be studied. A final course project will be assigned to students and they are asked to optimize the system and develop their computer code to determine the final optimized design variables.

Aerodynamics of Wind Turbines

The course attempts to survey the wind energy field with a particular emphasis on the aerodynamic aspects. The main objectives of the course include the following: (1) an introduction to wind energy and extracting energy from it, (2) the aerodynamic design of Horizontal/Vertical Axis Wind turbines by using the students' codes and available software, (3) wind resource assessment and wind farms, and (4) a discussion about the state-of-the-art topics related to wind study. To achieve these goals, the course includes independent study, team projects, group discussions, laboratory works, paper presentation, guest lectures, and scientific tours.

Pump & Pumping Systems

Turbopumps are widely used in many industrial applications. Considering the large number of installed and operating turbopumps, increasing their efficiency will result in considerable reduction of energy consumptions. The objective of this course is to provide proper knowledge about the principals of Pump and Pumping System. The course topics have been divided into two Parts. Part I includes information about pumps classification, centrifugal pump theory, designing turbopump components, losses and principals of operation. Part II presents pumping system basics, important parameters for pump operation, selection, pumping systems and performance improvement opportunities.

In each case, the factors that affect the performance of these systems will be highlighted. In addition, waste water treatment technologies such as Advanced Oxidation Process, and aeration will be introduced.

Special Topics in Oil, Gas, and Petrochemical Industries

This course provides broad technical information on refining processes and petroleum products, enabling a rapid immersion in the refining industry. We will start by refining processes, namely crude oil fractionation, catalytic reforming and isomerization, and hydrorefining processes. That will include origin, overall characteristics and classification of crude oils; basics of processes and types of catalysts; product yields and hydrogen production; and main features of impurities removal by catalytic hydrogen treatment. Then, we discuss main routes to major products and refining schemes. We will eventually have a look at the main economic features of refinery operation.
